If you have AT&T for your cell phone provider but you don't get good coverage in your home, AT&T is now offering microcells to improve your home coverage. These work by using your home broadband to transmit your cell phone signals when you are in your home. The microcells are not available everywhere yet, and they only work for 3G phones/devices. But if that's you, you can now get better coverage at home. You can read all the details on AT&T's site at http://www.wireless.att.com/learn/why/3gmicrocell/
